Ray, I have worked on these projects for the local utility where I work...Here are a few tips that I would suggest...
* I'm generalizing, and this might not apply to you, but many high rises have the meters in a lower floor in an electrical room, and then they run cables up to the living units where the breaker panels are installed. Because of this, you may not be able to easily add an additional circuit to your existing electric panel without a lot of work and/or a long run.
* In many cases, this leads to a separate meter solution in the electric room for your EV charging. So there needs to be electrical capacity in the gear that feeds your building to do that and physical space to do that (one EV charger may be able to be squeezed in, but the more you try to install the harder it gets). In our locale, the contractor would work with a utility Planner to get the new service (meter) installed (assuming that capacity and space are not an issue). Loads have to be verified within the switchgear that feeds the building to ensure that adding this new load will not exceed the nameplace ratings of the existing equipment, and the utility feed for the building will also be studied for similar effects.
* Once the okay is given, the utility will write a "Service order" and the contractor can start work. First they work out the solution in the meter room to install the new meter. Then they would run conduit and wire from the meter / breaker panel to where your car is. Sometimes they have to core drill through floors (which can be messy), and sometimes you get lucky and the car charging location is nearby. One of my customers was able to swap deeded parking places with another resident to get closer to the electric room.
* For this much trouble and expense, I would suggest pursuing a Level 2 charging solution. Level 1 is painfully slow, and some of that power goes to the battery cooling system when charging, so it's a higher percentage of loss at Level 1...
Check out this writeup for multi-unit dwelling charging at the Plugin Electric Vehicle Collaborative. There is a case study for CityFront Terrace that may be applicable to your situation. They put in 20 separate EV meters, and are charging residents $4,000 for their share of the meter (Service) installation, and that includes the conduit run and wire all the way to your parking space...Your situation may be smaller and more economical, but I just wanted to point out that example...
I hope that info helps....

That is a treasure trove of good information. In my enthusiasm to succeed I had not realized that the garage outlet wiring would have to come from my 4th-floor electrical panel, or, as you suggest, a separate meter and breaker need to be installed. A limitation for sure.
The links are helpful as well.
Thanks
